Selecting a location for your Lifestyle® stereo amplifierSelect a location for your Lifestyle® stereo amplifier and mount it according to the following guidelines.

CAUTION: DO NOT mount the amplifier on surfaces that are not sturdy enough, or that have hazards con-cealed behind them, such as electrical wiring or plumbing. The amplifier must be placed indoors. It is nei-ther designed nor tested for use outdoors or on boats.

Although the amplifier does not need to be situated close to either your Lifestyle® system or the accessory speakers, consider the following guidelines when selecting a location for your amplifier:

• Locate the amplifier indoors and within 8 feet (2.5 m) of a power outlet.

• Make sure that the amplifier is located within the reach of the supplied 30-foot audio input cable.

• Place the amplifier in an area where the maximum ambient temperature is less than 104°F (45°C).

• For optimum performance, place the amplifier in a well-ventilated area.

• DO NOT PLACE THE AMPLIFIER IN A COMPLETELY ENCLOSED AREA – If the amplifier is installed on a shelf, or in a bookcase, or inside an entertainment center, maintain 2.0 inches (5.0 cm) minimum clearance (Figure 2) on all sides of the amplifier with an open area of 3.0 inches (7.5 cm) minimum immediately above it to allow for air flow. If adequate ventilation is not provided, the amplifier will automatically protect itself by reducing its volume level in order to limit its temperature.

• DO NOT place the amplifier on any heat-sensitive surface, such as the finished surface of fine furniture. Like all electrical equipment, it generates some heat.

• DO NOT use the amplifier in a damp location. It is important to prevent moisture from getting into the unit.

Figure 2Required clearance between the amplifier and any material or surface.

• When mounting the amplifier on a horizontal surface like a floor or shelf (Figure 3), the amplifier’s rubber feet provide stability and prevent scratches.

Figure 3Horizontal surface mounting

• To mount the amplifier on a wall (Figure 4), remove the rubber feet and use the existing guide holes in the amplifier’s enclosure. See Figure 5 on page 6 for recommended mounting hardware.

Maintaining Your Lifestyle® Stereo Amplifier

Cleaning the amplifierThe amplifier, which is designed only for indoor use, may become dusty over time. To clean the amplifier, use only a soft, dry cloth to remove dust from the outside of the enclosure. Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives. Do not allow liquids to spill into any open-ings. Do not use any sprays near the amplifier.

Protecting outdoor wiringAlthough some Bose® speakers are designed and tested to stand up to outdoor weather conditions, the bare ends of the speaker wire can be affected by exposure to the elements. This is especially true of salt water exposure.

You may use a silicone caulking material, such as RTV adhesive, to protect speaker wire connections. It is commonly available at hardware stores. If you do use caulking, apply it only after the wires are connected and the knobs tightened down. Check the caulking annually, and re-apply as needed.

TroubleshootingIf you have a problem operating your Lifestyle® system after installing the Lifestyle® stereo amplifier, follow the guidelines below. For additional help, see the troubleshooting information in your system owner’s guide. If the problem still exists, contact your Bose dealer to arrange for service, or contact Bose Customer Ser-vice. Refer to the address list enclosed in the product packaging for correct phone numbers.

• If using a Model 20 music center, make sure the audio input cable is inserted into SPEAKER ZONE 2.

• If using a Model 5 music center for home theater (Lifestyle® 12 or Lifestyle® 8 sys-tems), make sure the amplifier audio input cable is plugged into the FIXED OUTPUTs on the music center. (Then the speaker output cable to the Acoustimass® module should be connected to the piggyback jacks on the audio input cable.)

• Disconnect any headphones.• Make sure the remote control switch settings are correct.

Only one speaker plays

• Check the wires connected to the speaker that does not play. • Make sure the wires are in good condition and are firmly connected at both ends.• See “Connecting speakers to your Lifestyle® stereo amplifier” on page 14.

One speaker still does not play

• Disconnect the wires from that speaker and the amplifier. Disconnect the other cable from its speaker, and connect that end of the cable to the speaker that does not play. If the speaker still does not play, the problem is in the speaker. If the speaker now plays, continue checking for the source of the problem.

• Disconnect the same cable from the amplifier. Connect it to the other outputs on the amplifier. If the speaker plays, the problem is in the original cable that was connected to that speaker. If the speaker does not play, the problem is in that channel of the amplifier.

Right and left stereo channels are heard on the wrong speak-ers.

• Check the speaker cable connections to be sure the cable connected to the SPEAKER OUTPUTS L at the amplifier are connected at the other end to the speaker on the left in your listening area.

• Check the speaker cable connections to be sure the cable connected to the SPEAKER OUTPUTS R at the amplifier are connected at the other end to the speaker on the right in your listening area.

Bass or treble is weak

• Check the speaker wire connections. Make sure the wires are connected + to + and – to –.

• See “Connecting speakers to your Lifestyle® stereo amplifier” on page 14.

Interference • Make sure the speaker wires are firmly inserted in the terminals on the back of the speaker and on the amplifier rear panel. Check to be sure no wires are touching across terminals.

• See “Connecting speakers to your Lifestyle® stereo amplifier” on page 14.

Remote does not adjust the volume

• Be sure the 1/8” mini-plug is firmly inserted in the SYSTEM CONTROL 2 jack.• If you are using an RC-20 or RC-5 remote control, make sure the remote control

switch settings are correct.

Volume suddenly decreases

• Lower the volume setting to see if the level returns to normal. If so, the sudden loss of volume was an intentional action of the amplifier’s overload protection feature. This engages automatically if the volume is set too high and is overdriving the speakers. Choosing a lower setting should ensure continuous, even volume.

Zone 2 does not work at all

• If you are using a Lifestyle® DVD system, the stereo amplifier will not work unless “Zone 2 Protocol” in the system settings menu is set to “Legacy”. For more informa-tion, consult your Lifestyle® DVD system’s owners guide.
